Energy from Death

Animals
are a source of energy-rich food even after they die. Here we can
see beetles, flies, bacteria, and other organisms feasting on carcasses.
They get their energy from rotting flesh, just as we get energy
from the food we eat. Scavengers break down the tissues of dead
animals, releasing nutrients that would otherwise remain trapped
inside. This action recycles proteins and minerals from the dead
animal's body, enriching the soil for plants to grow, and providing
food for other creatures to consume.
